Definitions

  • the invention relates to a device for air purification for ventilation and air conditioning systems according to the preamble of claim 1.
  • Air purification devices are well known and their importance is increasing with increasing air pollution in particular of the fine dust content constantly. Depending on the degree of efficiency and application, they are designed as pocket filters, compact filters or closed filter cells, with pocket filters being the most widely used.
  • the filters are measured according to the European standard EN 779 / EN1822 and due to the efficiencies (particle counting) resp. the degree of separation (by weighing) divided into different air filter classes.
  • the quality or the structure of the filter material used, the filter surface and the filter material (glass or synthetics) determine the properties of a filter in addition to the mentioned structural differences.
  • the pressure loss and thus the energy consumption of the filter system are of decisive importance for the operation.
  • the energy consumption can be significantly different for similar filters, even the same filter class.
  • the initial pressure losses in the sales documents are usually still close to each other, they increase very differently in the course of operation from filter type to filter type.
  • a device for air purification for a device for air purification according to the document US-A-5,622,543 are provided in a formed air duct a plurality of successively arranged filter or plates.
  • the air passes through a wire mesh grid and then through a perforated plate formed as an anion generator This purpose is electrically connected to a high voltage generator and generates an electromagnetic field.
  • a dust collector and then an activated carbon filter is arranged.
  • the disadvantage is that the entire arrangement with these multiple filters and plates has a very low efficiency and that doing this perforated plate with the rhomboid holes such a speed reduction to the air flowing through causes the dust particles instead of the subsequent dust collector already in this perforated plate deposit and clog those holes quickly.
  • an electrostatic filter which is formed by a housing and has both an inlet and an outlet at the front.
  • the intake air is conveyed through a pre-filter and the electrostatic filter and from there to the fan and the outlet.
  • the electrostatic filter consists of a fan-shaped cell with walls arranged parallel to each other at a distance, which are partly provided with different dimensions and electrodes arranged therebetween.
  • the electrostatic filter is not followed by a filter.
  • the air purification from the prefilter and then significantly from this labyrinth-shaped electrostatic filter is carried out. In this case, such an air resistance is generated that a lot of energy is consumed in an uneconomical manner for the fan.
  • ESP electrostatic precipitator
  • EP-A-1 547 693 are arranged in a box-shaped housing one behind the other a pre-filter, an ionization, a dust filter, a passage means and a catalyst part.
  • the passage device contains electrodes and the subsequent catalyst part has a honeycomb-shaped structure. This air purifier is not suitable for ventilation and air conditioning, because this prevails too high air resistance.
  • the present invention has for its object to provide a device of the type mentioned, with an increase in efficiency and a reduction in the efficiency of waste and a substantial retention the pressure loss during the entire operating time is achieved under normal outside air conditions.
  • the efficiency of a particular filter is increased so that the dust penetration (dust penetration) can be approximately halved.
  • the initial efficiency drops during a normal operating time (for example, 6,000 hours) only insignificantly, which gives the operator a crucial security and this with only insignificantly increasing pressure loss.
  • the energy costs can be kept constant and low.
  • the dust agglomerator immediately upstream of the air filter according to the invention enlarges the fine dust carried by the air by agglomeration in such a way that it can be better separated with a simple air filter.
  • the dust is preconditioned by the agglomerator.
  • the subject matter of the invention has only a single DC high-voltage field, which increases the dust particles by ionization and subsequent agglomeration, as a result of which the dust in the downstream air filter of industry-standard design is deposited more highly.
  • the majority of the same polarity charged deposited dust particles also form an electrostatically active surface in the air filter, which additionally reinforces the dust in the filter fabric and reduces the unwanted dust shedding.
  • the agglomerator effect is constantly renewed thanks to the electrostatic field and the degree of separation remains largely maintained during the operating time at the initially high level. This effect occurs in glass fibers as well as in synthetic filter media.
  • the dust particles present in the air are converted in the dust agglomerator into larger, reduced in number dust particles, which can be deposited more effectively.
  • the filter medium thus does not need to be so tightly meshed, which means less pressure loss and thus lower energy consumption. In other words, the same cleaning effect can be achieved with a "worse" filter. Profitability calculations include the additional energy consumption for the high-voltage rectifier.
  • the device is also ideally suited for cost-effective retrofitting existing filter systems to higher efficiencies, without fans and drive motors must be replaced because of the required higher pressure losses.
  • the device also eliminates the inherent disadvantage of traditional electrostatic precipitators by eliminating any separation effect of the electrostatic precipitator in case of power failure. In the device according to the invention, however, the normal degree of separation of tissue filter is retained in the event of a power failure.
  • Fig. 1 schematically shows an apparatus for air purification, in particular for ventilation and air conditioning systems, which is mounted in an air duct 10 formed by a channel housing 25, through which the air to be cleaned in the flow direction S is conveyed.
  • It is, for example, a standard channel for a filter cell, which usually has a cross section of 610 ⁇ 6.10 mm.
  • the amount of air can be, for example, 2700 m 3 / h or 3400 m 3 / h, which corresponds to an air velocity in the channel of 2 m / s or 2.5 m / s.
  • This device in the air duct 10 is associated with an air filter 11, which serves for the separation of dust particles present in the air. It is a commercially available pocket or compact filter, as those in various categories of air filters are available on the market. Such air filters are usually made of a close-meshed synthetic fabric.
  • the air filter 11 is immediately upstream of a dust agglomerator 12, which also in Fig. 2 is shown simplified.
  • the dust agglomerator 12 has a number of spaced-apart electrodes 16 and sheet-metal fins 15, wherein the wire-like electrodes 16 and the sheet metal fins 15 are arranged alternately and with the electrodes 16 in the air duct, a voltage field, in particular a DC field, can be generated.
  • the electrodes 16 and sheet metal fins 15 are arranged in series in the frame-shaped dust agglomerator 12 in transverse alignment with the air duct 10.
  • the sheet-metal fins 15 extend in this case with their elongated cross-section in the air flow direction S and they are advantageously arranged parallel to one another at a uniform distance, together with the electrodes, wherein the electrodes 16 are positioned approximately in the central region of the sheet-metal fins 15.
  • They may each preferably be formed as a wire electrode made of tungsten or another special steel, which extends in the longitudinal direction of the rectangular lamellae 15 (counter electrodes).
  • the electrodes could also be wave-shaped and thus be tensioned like a spring in the dust agglomerator.
  • the electrodes 16 are connected to the generation of the DC voltage field via the connecting lines 22, 23 to a high voltage rectifier 13, and this is in turn connected via a line 14 to the mains.
  • the voltage of the high voltage rectifier 13 may be e.g. between 5 kV and 12 kV.
  • the high-voltage rectifier 13 ' can also be integrated directly in the dust agglomerator 12 so that they can be exchanged together as a single structural unit and thus only a plug connection for the power supply (eg 230 V AC) of this rectifier must be present.
  • This high-voltage rectifier 13 ' is dimensioned so that it does not protrude to the frame of the agglomerator 12, so that the frame produced in standard size can be inserted into a correspondingly normalized channel without this channel having to be specially adapted.
  • the frame-shaped dust agglomerator 12 is designed as a plug-in module and transversely in the channel housing 25 in front of the air filter arranged parallel to it 11 fixable. It can also be directly hung or attached to the filter frame or the filter and be installed or removed as a common unit in a system. By optimizing the design, the depth t of the dust agglomerator 12 can be kept so low that even existing air conditioners or systems can be retrofitted with it.
  • the depth of such agglomerator 12 is preferably between 40 and 60 mm.
  • the distances between the electrodes and the lamellae are also selected so as to give optimum conditions with regard to the air resistance of the agglomerator 12, to the electrostatic charge in the filter and to the electrostatic influence of the dust. Between the electrodes and the fins, a distance of 10 to 50 mm is preferably provided. In principle, the lamellae could also be designed almost like a wire.
  • the dust agglomerator 12 is preceded by a dash-dotted prefilter 19, which may also be provided as a commercially available filter.
  • This pre-filter 19 is preferably formed coarsely meshed so that it must protect the agglomerator 12 only of coarse dirt particles (insects or the like).
  • the dust agglomerator 12 connected to the high-voltage rectifier 13 has a single DC field, so that no dust separation takes place in the agglomerator.
  • the air is ionized, and the dust is collected only in the downstream of the dust agglomerator 12 air filter 11.
  • the majority gleichpolig charged dust particles form an electrostatically active surface in the air filter 11, which additionally reinforces the dust in the filter fabric. This is also particularly effective when the air to be purified contains liquid droplets, for example oil particles, which are better separated from the air with the device according to the invention.
  • FIG Fig. 4 shows the basic efficiency curve by way of example as a function of the operating hours and with reference to a dust diameter of at least 0.4 ⁇ m.
  • the efficiency can be maintained permanently at almost 80%, while using a same pocket filter results in an efficiency that drops to less than 30% ,
  • the dust particles present in the air are converted in the dust agglomerator 12 into larger, reduced in number dust particles, which can be deposited more effectively.
  • the air filter 11 needs to be less close-meshed, which also means less pressure loss at a certain efficiency. In other words, the same cleaning result can be achieved with a "worse" filter, or the same filter is suitable for more compact solutions (with shorter air filters).
  • the device according to the invention is economically more economical than conventional air purification devices with comparable efficiency, despite the need for additional electrical energy for the dust agglomerator, since the systems can be equipped with filters of a lower class and thus smaller pressure loss (energy consumption and acquisition costs).
  • the benefits of the agglomerator are particularly evident in the submicron particle range where Brownian motion of the molecules is effective.
  • the Brownian motion is enhanced by the applied field energy (kinematic coagulation), which is why the device according to the invention is used particularly in submicron fine dust and in nanotechnology.
  • inventive agglomerators but also the filter cells can be preceded by whole filter walls in large plants.
